Abstract

Recent attention has been given to animal feeding and its impact on human nutrition. Animal feeding is essential for meeting human dietary needs, making it a subject of significant interest and investigation. This review seeks to outline the current understanding of this disciplinary area, with a focus on key research areas and their potential implications. The initial part of the paper discusses the importance of animal feed resources and recognizes their crucial role in guaranteeing sufficient nutrition for both humans and animals. Furthermore, we analyzed the categorization of animal feeds based on the guidelines established by the National Research Council. This approach offers a valuable structure for comprehending and classifying diverse types of animal feed. Through an examination of this classification, we gain an understanding of the composition and nutritional content of various feedstuffs. We discuss the major categories of metabolites found in animal feed and their impact on animal nutrition, as well as their potential health advantages for humans. Flavonoids, polyphenols, tannins, terpenoids, vitamins, antioxidants, alkaloids, and essential oils are the primary focus of the examination. Moreover, we analyzed their possible transference into animal products, and later we observed their occurrence in foods from animal sources. Finally, we discuss their potential to promote human health. This review offers an understanding of the connections among the major metabolites found in feedstuffs, their occurrence in animal products, and their possible impact on the health of both animals and humans.

Abstract

Over the last several years, the models for organic waste management have changed to implement circular economy in the productive cycle. In this context, new scenarios have emerged, where the management of different organic waste streams by composting is conducted with decentralized models that manage organic wastes in a more local way. However, in these new models, the standardization of the process control and of the end-product characteristics is necessary to guarantee the quality and agronomic value of the compost obtained, avoiding potential risks for human health and the environment. Thus, the aim of this work was to study two different scenarios of community composting of the organic fraction of municipal solid waste separately collected in order to guarantee the effectiveness and reproducibility of the composting processes and the quality of the composts obtained. For this, the development of the process and the characteristics of the composts at agronomic, hygienic–sanitary and environmental levels were assessed in real conditions and during three cycles of the process. The results obtained show high similarity among the different composting cycles, indicating an important degree of reproducibility among the processes. In addition, the composts obtained showed a good sanitary quality, absence of phytotoxicity and low contents of potentially toxic elements, which guarantee their use in agriculture without posing any risk to human health and to the environment., This research has been financed by the research project NEOCOMP (ref. PID2020-113228RBI00) funded by MCIN/AEI/10.13039/501100011033, and it was supported by the Spanish Ministry of Universities with a PhD contract (FPU21/01207) to the first author., Postprint (published version)

Abstract

This study aimed to describe the development of the Perceived Therapist's Knowledge about Gender Identity Diversity Scale and to preliminarily validate this scale by describing its psychometric properties. This research instrument was constructed based on the existing literature and recommendations for instrument development. Initially, a 36-item scale was devised to assess perceived openness and knowledge about gender identity diversity in therapy. The content validation process involved 12 expert judges, leading to a refined 25-item scale. Participants consisting of 57 trans and non-binary Puerto Rican individuals completed the scale. Exploratory factor analysis revealed a unidimensional structure, supporting a single factor named "perceived knowledge about gender identity diversity in therapy." The final scale demonstrated excellent reliability (α = 0.978; Sα = 0.980; ω = 0.979), indicating strong internal consistency. This validated scale contributes to assessing primarily Hispanic trans and non-binary individuals' perceptions of their therapists' knowledge about gender identity diversity. [ABSTRACT FROM AUTHOR]

Abstract

Sección: Poniendo en claro [ES] La escasez de órganos humanos para trasplante ha propiciado la búsqueda de otras alternativas, como la posibilidad de utilizar animales como donantes, lo que se conoce como xenotrasplante. El cerdo se ha convertido en la especie donante más prometedora tanto por su similitud anatómica y fisiológica con el ser humano, como por la disponibilidad de metodologías de modificación genética, que han permitido la obtención de modelos porcinos que permiten hacer frente a los riesgos del xenotrasplante. Estos riesgos están asociados con el rechazo inmunológico, la desregulación de la coagulación y la presencia de retrovirus endógenos porcinos. Aunque los resultados de los ensayos preclínicos en primates varían considerablemente, alcanzando diferentes tiempos de supervivencia en función del órgano trasplantado, la inactivación del gen que codifica el antígeno α-Gal ha resultado imprescindible para superar el rechazo hiperagudo, que es la primera y más drástica barrera inmunológica. Los hitos que se han logrado en los últimos años, incluyendo las pruebas clínicas recientes con seres humanos a los que se han realizado trasplantes de riñón o corazón de cerdos modificados genéticamente, acercan un paso más el traslado de los xenotrasplantes a la práctica clínica
